Abstract：Reaming while drilling (RWD) is often accompanied by violent vibration causing early failure of reamer and slower rate of penetration.In order to reduce lateral vibration of reamer and prolong their life, a nonlinear dynamic finite element model for drilling tools-rock interaction was established to analyze effects of number of drilling collars between pilot bit and reamer on drilling tools’ drill pressure distribution, lateral vibration intensity and rate of penetration. The results showed that placing appropriate number of drill collars between pilot bit and reamer can effectively reduce drilling tools’ reaming pressure ratio and lateral vibration intensity of reamer, and improve rate of penetration (ROP); designing reamer placed below and far away from the neutral point can reduce the risk of its failure; under the working condition here, the optimal number of drill collars between pilot bit and reamer is 3; the study results can provide a certain guidance for RWD drilling tools combination design and prolonging reamer life.
